Jurassic Park Wiki

Euoplocephalus was an ankylosaurid dinosaur from the Late Cretaceous of North America. This dinosaur weighed almost 3 tons and had a width of 2 meters and was around 5.5 meters long. Euoplocephalus was equipped with fused bone plates on its back that acted as body armor as well as a pair of horns that protruded from the back of the neck, possibly as a defense against being grabbed by the neck. For defense Euoplocephalus was armed with a foot wide tail club that could be swung like a medieval flail and had the ability to break bone. In addition Euoplocephalus also supported a pair of armored eyelids, like Ankylosaurus.

Wikipedia has a more detailed and comprehensive article on Euoplocephalus


Euoplocephalus had 9% of its total genome completed during construction of the original park;[1] implying that it was planned to be an attraction some time in the future.

It is known that Euoplocephalus was subject to cruelty at some time in the past, although it is unknown if there are any surviving populations remaining.[2]


Euoplocephalus was successfully created by InGen on Isla Sorna for Jurassic Park on Isla Nublar. It is assumed they lived in the Triceratops Territory with Triceratops and possibily Styracosaurus.

By August 16, 1989, there were 16 Euoplocephalus living in the park and they were Version 4.0.[3][4]

By the end of the InGen Incident there were only 9 that survived,[5] the ones that did not most likely being killed by the escaped Tyrannosaurs and Velociraptors. ultimately the surviving Euoplocephalus were all killed by the Costa Rica Napalm Bombing that followed after the incident.[6]

It is unknown if there were ever any populations that survived on Isla Sorna.
